T/YNRZ 024-2024 Black Tiger Planting Technical Specifications

Scope

Scope: This document specifies the technical requirements for the cultivation of Black Tigers, including site selection, pre-planting preparation, planting, site management, vine management, flower thinning, artificial pollination assistance, fruit and vegetable production, fruit bagging, and pest and disease control. This document is applicable to the management of Black Tiger cultivation; Main technical content: 1. Site selection 1.1 Environmental conditions: Suitable for growing in shaded and humid environments with an altitude of 600 m to 1800 m, an average annual temperature of 16°C to 22°C, annual precipitation of 800 mm to 1300 mm, and an average annual relative humidity of 70% to 80%. 1.2 Soil conditions: Soil pH value of 5.0 to 6.5, with a thick layer of soil and good drainage. Sandy loam is the most suitable. 2. Pre-planting preparation 2.1 Digging planting ditches: Dig planting ditches 40 cm to 50 cm deep and 70 cm to 80 cm wide. The length, width, and depth of the trellis holes should be 60 cm, 60 cm, and 50 cm respectively. The distance between fence-type trellis holes is 3 m, and the distance between trellis holes is 2 m. After digging the ditches, first fill them with 10 cm to 20 cm of topsoil, mix the composted organic fertilizer with the soil, and backfill and compact it in 2 to 3 stages. After backfilling the planting ditches, level the entire field. 2.2 Setting up trellis frames 2.2.1 Fence-type trellis frames: Stakes spaced 4.0 m × 5.0 m are suitable. The trellis height should be 1.8 m to 2.0 m, and the trellis surface should be made of suitable-sized plastic steel wire or iron wire, forming a "#"-shaped grid with a width of 0.6 m to 0.8 m. 2.2.2 Trellis frames: Stakes spaced 2.0 m × 3.0 m are suitable. The trellis height should be 2.0 m to 2.3 m, and the trellis surface should be made of suitable-sized plastic steel wire or iron wire, forming a "#"-shaped grid with a width of 0.6 m to 0.8 m. 3. Planting 3.1 Time: It is suitable to plant from
